One peice design: now made of polypropylene for extra strength, filters are no longer snapped together, and won’t break when servicing. Slots, provide less surface area for solids to attach, rather than mesh screens, and promote the sloughing action. Zabel 4x18 and 4x22 filters can be used with ANY 4” tee, including our PL-68 tee and our Versa-Tees.
